In the ever - evolving landscape of electronic devices, where miniaturization and high - performance are the driving forces, our 4 - layer soft - hard combined (rigid - flex) FPC (Flexible Printed Circuit) PCBs emerge as a game - changing solution.
Constructed using FPC material, these PCBs offer the unique advantage of flexibility, allowing them to bend and conform to the space constraints within modern electronic products. The 4 - layer structure provides a well - balanced combination of mechanical stability and electrical performance. The 1oz copper thickness is carefully selected to ensure efficient power and signal transmission while maintaining the flexibility of the board.
The board thickness of 1.6mm is optimized to provide sufficient mechanical support without compromising the flexibility required for specific applications. One of the standout features of our PCBs is the ultra - fine pitch design, with a minimum aperture of 0.15mm and minimum trace width/spacing of 0.065mm. This enables the integration of a large number of components and complex circuits on a relatively small area, facilitating the development of highly compact and feature - rich electronic devices.
The Immersion Gold (ENIG - Electroless Nickel Immersion Gold) surface treatment offers multiple benefits. It provides excellent corrosion resistance, protecting the PCB from environmental factors that could degrade its performance over time. Additionally, ENIG ensures reliable solderability, enabling consistent and high - quality component attachment during the assembly process. This is crucial for maintaining the long - term reliability of the electronic device.
